| 摘要: |
| 提出一种主站终端化的分布式保护信息应用系统,以实现远方不停电定值整定、投切软压板、切换定值区、复归保护信号等综合应用功能为目的。该系统以变电站为单位建设功能完备的分布式保护信息应用子站,实现微机保护的核心应用,并对多种不同报文格式、不同传输协议的保护的解析处理,转换成所研制的统一内部交换标准协议。远方主站则为免维护的终端化模式,尽量减少远方主站的复杂性和传输压力。详细阐述了该支持系统实现的机制和特点,并在地区电业局实际运用,证明了其可用性和优势。 |

| Abstract: |
| A distributed protection information system with the master station as a terminal is proposed,which realizes integrated application functions,such as on - line remote setting of protective values,remote enabling and disabling of soft functions,remote switching of setting groups,remote resetting of protection signals,and so on. It takes each substation as a basic unit to set the distributed information substation with full functions,which implements the kernel functions of microcomputer protection and converts different message formats and transmission protocols into internal exchange standard format and protocol. The master station is of maintenance-free terminal mode to reduce its complexity and transmission pressure. The mechanism and features of information system is expounded and its application in regional electrical bureau proves its usability and advantage. |
